You’ve finally hopped on the Basal Body Temp (BBT)-train and are ready to track your cycle with way more accuracy than just by looking at the calendar each month.
But now you’re wondering if you’re placing your basal body thermometer in the right spot!
Because yes, 𝒘𝒉𝒆𝒓𝒆 you place your BBT thermometer matters! Researchers found a 0.3-degree difference in temperature depending on where you take your temp in the area just below your tongue or if you stick it way in the back.
So what should you do? Lift your tongue up and put the thermometer in the back on the right or the left side of the membrane in the middle, the frenulum. This area is called the left or right (depending on which side) posterior sublingual pocket. Close your mouth and wait for the beep.
And that’s all there is to it 😊
